The program is compact: the basic installation of version 4.30 occupies 1.6 MB, and a full install with all plugins (not required for basic functionality) occupies about 10 MB. The program can be downloaded directly to a U3 compatible device.

It supports viewing and saving of numerous file types including image formats such as BMP, GIF, JPEG, JP2 & JPM (JPEG2000), PNG (includes the optimizer PNGOUT), TIFF, camera RAW, ECW (Enhanced Compressed Wavelet), EMF (Enhanced Windows Metafile), FSH (EA Sports format), ICO (Windows icon), LDF (LuraDocument format), LWF (LuraWave format), PCX (Zsoft Paintbrush), PBM (Portable bitmap), PDF (Portable Document Format), PGM (Portable graymap), PPM (Portable Pixelmap), TGA (Truevision Targa), WebP and viewing of media files such as Flash, Ogg Vorbis, MPEG, MP3, MIDI, and text files.[9][10]

While viewing images, there are several fit-to-screen scaling options and an automatic slideshow function. The viewer can open in sequence all the image-files and video clips (of most formats, including AVCHD) contained in a folder. Slideshows can contain still images and video clips; useful with current digital cameras.[citation needed]

IrfanView can create screensavers and slide shows from collections of images with optional accompanying MP3 audio. These can be saved as stand-alone executables which run on Windows computers without IrfanView installed.

For slideshow creation, screensaver creation and batch image translations, preset image processing steps can be applied to selected sets of images.

IrfanView can create icons by converting common graphic files into .ico format. It supports Adobe-compatible 8BF image processing filters, including many freely downloadable ones, primarily for application to whole images.

The program has TWAIN support for retrieving images from scanners, and extended support for taking screenshots.

Image editing includes crop, resize, and rotate. Images can be adjusted by modifying their brightness, contrast, tint, and gamma level[11] manually or automatically, and by converting them between file formats. Many of these changes can be applied to multiple images in one operation using batch processing. Resize can be applied towards the display of animated GIF images to make them larger in either windowed or full-screen modes. Lossless functions can be applied to JPG images in order to optimize the files without change to the displayed image.

IrfanView can direct the active image to open in an external graphics editor (Adobe Photoshop, for example) if it is installed.

In English by default, the program is internationalized in over twenty languages.
